Hi there ROCK, here I am again. Anyway, that's a real tight fit between the header tubes & the steering shaft. I hope that I won't have things that close when I fit the header in next to the steering box. On 1965-'70 Chevy "B" body chassis' the steering box is located kinda close to the firewall & under the (brake) master cylinder. Right next to the engine. Also, the tie rod is under the engine, & in back of the crossmember. That will also requiere the use of a "rear sump" eldo pan & pick up tube. Well, that's it for now. Later.
